4 DE BALLON CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The two 4 DE BALLON CLOSE sales from November 2001 and December 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the November 2001 sale was for 55% above the HPI. So the extrapolation line tracks at 55% above the HPI over time, until the December 2025 sale, where it falls to 19% above the HPI. The line then continues to track at 19% above the HPI.
